[0051] The specific embodiments of the present application have been shown by the above drawings, and will be described in more detail hereinafter. These drawings and written descriptions are not intended to limit the scope of the concept of the present application by any means, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0052] The exemplary embodiments will be described in detail herein with reference to the attached drawings. The description of the exemplary embodiments is intended to apply to all alternative embodiments, as would be understood by persons skilled in the art. To that end, the following description is not intended to limit the exemplary embodiments to a single exemplary embodiment containing all features that can be presented. Rather, the exemplary embodiments contain features that can be combined with each other in various combinations in a multitude of different embodiments, as would be understood by persons skilled in the art. Moreover, well-known functions or constructions are not described in detail since they would obscure the exemplary embodiments provided herein with no constructive benefit.

[0053] Batteries generate heat during charging and discharging. Excessive temperature can cause thermal runaway, leading to fire or explosion. By monitoring temperature, measures can be taken in time to avoid dangerous situations. Battery performance, such as capacity, efficiency, and power output, is closely related to temperature. An appropriate temperature range can ensure the best performance of the battery. Excessive or low temperature will affect the chemical reaction rate of the battery, thus affecting its performance. At the same time, abnormal voltage changes may be an early sign of internal battery failure, such as short circuit, overcharge or overdischarge. Therefore, timely detection of temperature and voltage changes can help prevent failure.

[0054] In the related art, the temperature and voltage of the battery can be obtained by a collection device. In one collection device, the collection device includes a circuit board, a temperature collector, and a conductive metal sheet. The temperature collector is welded to the circuit board, and the two ends of the conductive metal sheet are connected to the battery electrode and the circuit board, respectively. The temperature on the surface of the battery is transmitted to the temperature collector through the conductive metal sheet. However, the temperature collected by the collection device is transmitted through multiple media, and the distance between the temperature collector and the battery is far, and energy loss occurs during heat transfer. Therefore, there is a problem of inaccurate data collection.

[0055] In another collection device, the collection device includes a collection terminal, a circuit board, a temperature collection piece, and a voltage collection piece. One end of the collection terminal is directly welded to the busbar, and the other end is provided with the circuit board. The circuit board is provided with the voltage collection piece and the temperature collection piece. Similarly, the temperature collected by the collection device is transmitted through the collection terminal, resulting in the problem of inaccurate data collection of the collection device. In addition, the above two collection devices cannot be adjusted according to the structure of the specific battery, and cannot reasonably utilize the space around the battery. The existing temperature collection device has the problems of poor use performance, large measurement deviation, and inaccurate data collection.

[0056] In view of this, the embodiments of the present application provide a collection device, a battery assembly and an electrical equipment. The collection device is used for collecting temperature and voltage, and comprises a voltage collection part and a temperature collection part. The collection device comprises the voltage collection part and the temperature collection part. The voltage collection part has a voltage collection end, which is used for being connected to the battery. The temperature collection part has a temperature collection end. In the height direction of the collection device, the temperature collection end of the temperature collection part and the voltage collection part are stacked, and the temperature collection end is arranged close to the voltage collection end.

[0057] In the height direction of the collection device, by stacking the temperature collection end of the temperature collection part and the voltage collection part and arranging the temperature collection end close to the voltage collection end, the temperature collection end of the temperature collection part is as close to the battery as possible, which can more accurately reflect the real temperature of the battery. This layout reduces the interference of the external environment on temperature measurement, improves the accuracy of data collection of the collection device, and by stacking the temperature collection end of the temperature collection part and the voltage collection part, the space can be effectively utilized, and the occupation of the space around the battery is reduced. This compact layout helps to integrate more functions in a limited space.

[0058] The technical solutions of the present application and how the technical solutions of the present application solve the above technical problems will be described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of the present application will be described below with reference to the drawings.

[0059] In the first aspect, with reference to Figures 1 to 3 The embodiments of the present application provide a collection device for collecting temperature and voltage, which comprises a voltage collection part 100 and a temperature collection part 200.

[0060] The voltage collection part 100 has a voltage collection end, which is used for being connected to the battery 400.

[0061] The temperature collection part 200 has a temperature collection end. In the height direction of the collection device, the temperature collection end of the temperature collection part 200 and the voltage collection part 100 are stacked, and the temperature collection end is arranged close to the voltage collection end. The height direction of the collection device refers to the direction shown in Figure 1 .

[0062] Exemplarily, the charging and discharging process of the battery 400 involves chemical reactions on the electrode 410, and the rate of these reactions is closely related to temperature. The battery 400 generates heat during use, especially during high load or rapid charging and discharging. The temperature change of the electrode 410 can provide information about the health status of the battery 400, such as whether there is abnormal heating, which may be a sign of aging or internal failure of the battery 400.

[0063] The battery 400 can generate gas during charging and discharging, leading to changes in internal pressure. Changes in the voltage of the electrode 410 can reflect the generation of gas inside the battery 400, which is very important for assessing the safety and sealing of the battery 400.

[0064] Abnormal temperature and voltage can indicate potential safety risks, such as thermal runaway or internal short circuit. By monitoring these parameters, measures can be taken in time to prevent accidents. In the embodiments of the present application, the acquisition device is used to acquire the temperature and voltage of the electrode 410 of the battery 400.

[0065] In the height direction of the acquisition device, the temperature acquisition end of the temperature acquisition piece 200 and the voltage acquisition piece 100 are stacked, and the temperature acquisition end is arranged near the voltage acquisition end. In this way, the temperature acquisition end of the temperature acquisition piece 200 is as close to the battery as possible, which can more accurately reflect the true temperature of the battery. This layout reduces the interference of the external environment on temperature measurement, improving the accuracy of data acquisition by the acquisition device.

[0066] By stacking the temperature acquisition end of the temperature acquisition piece 200 and the voltage acquisition piece 100, space can be effectively utilized, reducing the occupation of space around the battery. This compact layout helps to integrate more functions in a limited space.

[0067] Different types of batteries 400, such as lithium-ion batteries 400, lead-acid batteries 400, nickel-hydrogen batteries 400, etc., may have different electrode 410 structures in design. Some battery 400 designs may require electrodes 410 of different heights to optimize electrochemical reactions or battery 400 performance. In some embodiments, the voltage acquisition piece 100 is a shape-changing piece. Shape-changing piece refers to a material or structure that can change shape in response to external pressure or stress changes. The shape-changing piece design allows the voltage acquisition piece 100 to deform within a certain range, thereby adapting to batteries 400 with different structural characteristics. This flexibility allows the same acquisition device to be used for multiple battery 400 configurations, reducing the need for adaptation to different battery 400 designs.

[0068] The shape-changing piece can ensure contact with the electrode 410 by deforming, thereby ensuring stable acquisition of the voltage signal, which helps to improve the accuracy of voltage measurement and reduce measurement errors caused by poor contact.

[0069] In some embodiments, the voltage collection piece 100 comprises a nickel sheet. The nickel sheet has electrical conductivity and corrosion resistance, making it suitable for voltage collection. The mechanical strength and elasticity of nickel also make it suitable for use as a deformation piece, which can withstand certain mechanical stress without damage. The deformation piece design can simplify the installation process of the collection device, as it can automatically adjust to changes in the height of the electrode 410. This reduces the need for precise alignment during installation. At the same time, the nickel sheet as the voltage collection piece 100 can provide reliable electrical contact, ensuring the accuracy and stability of voltage measurement.

[0070] In other embodiments, the voltage collection piece 100 can also be a copper sheet. Copper has good mechanical strength and ductility, and is easy to process into various shapes and thicknesses.

[0071] In yet other embodiments, the voltage collection piece 100 can also be an aluminum sheet. Aluminum is easy to process and shape, suitable for various manufacturing processes.

[0072] In some embodiments, the temperature collection piece 200 comprises a thin film thermistor. A thin film thermistor is an electronic component used for temperature measurement and control. It uses the property of a material's resistance changing with temperature to detect temperature changes.

[0073] In other embodiments, the temperature collection piece 200 can be a resistance temperature detector. A resistance temperature detector utilizes the property of a metal (usually platinum) whose resistance changes with temperature. Resistance temperature detectors have high precision and stability.

[0074] In yet other embodiments, the temperature collection piece 200 can be a semiconductor temperature sensor. A semiconductor temperature sensor is based on a diode or integrated circuit temperature sensor.

[0075] As an implementable embodiment, the temperature collection piece 200 is arranged on the side of the voltage collection piece 100 away from the battery 400. The temperature collection end of the temperature collection piece 200 is arranged as shown in the dashed box in FIG. 1A. Figure 1

[0076] In some embodiments, the voltage collection piece 100 is connected to the electrode 410 of the battery 400, and the voltage collection piece 100 can obtain the voltage of the electrode 410. The temperature collection end of the temperature collection piece 200 is arranged on the side of the voltage collection piece 100 away from the battery 400. Arranging the temperature collection piece 200 as close to the battery 400 as possible can more accurately reflect the true temperature of the battery 400. This layout reduces the interference of the external environment on temperature measurement, improving the accuracy of data collection by the collection device.

[0077] ​By placing the temperature acquisition piece 200 on the side of the voltage acquisition piece 100 away from the battery 400, the space can be effectively utilized, and the occupation of the space around the battery 400 is reduced. This compact layout helps to integrate more functions in a limited space.

[0078] As an implementable embodiment, the temperature acquisition piece 200 is placed on the side of the voltage acquisition piece 100 close to the battery 400.

[0079] In other embodiments, the voltage acquisition piece 100 is connected with the electrode 410 of the battery 400, and the voltage acquisition piece 100 can acquire the voltage of the electrode 410. The temperature acquisition end of the temperature acquisition piece 200 is placed on the side of the voltage acquisition piece 100 close to the battery 400, so that the temperature acquisition end can directly acquire the real temperature of the battery 400. This layout reduces the interference of the external environment on the temperature measurement, and improves the accuracy of the data acquisition of the acquisition device.

[0080] By placing the temperature acquisition piece 200 on the side of the voltage acquisition piece 100 close to the battery 400, the space can be effectively utilized, and the occupation of the space around the battery 400 is reduced. This compact layout helps to integrate more functions in a limited space.

[0081] As an implementable embodiment, the acquisition device further comprises an acquisition circuit board 300, and the voltage acquisition piece 100 and the temperature acquisition piece 200 are connected with the acquisition circuit board 300.

[0082] Exemplarily, the acquisition circuit board 300 is responsible for receiving signals from the voltage acquisition piece 100 and the temperature acquisition piece 200. These signals may be analog, and need to be converted into digital signals by the acquisition circuit board 300 for further processing. The acquisition circuit board 300 may contain signal conditioning circuits to amplify, filter or calibrate sensor signals, ensuring the accuracy and stability of the data.

[0083] In addition, by connecting the voltage acquisition piece 100 and the temperature acquisition piece 200 to the same acquisition circuit board 300, the acquisition device design is more compact and integrated, reducing wiring complexity and potential connection problems.

[0084] Exemplarily, the acquisition circuit board 300 has a distance from the electrode 410 to prevent electrical short circuit and other potential safety hazards. Sufficient distance also helps heat management to prevent the heat of the battery from directly affecting the performance of the acquisition board.

[0085] The nickel sheet as a deformation piece can maintain good contact when the height of the electrode 410 changes through deformation, and in addition, the deformation piece can adjust the distance between the acquisition circuit board 300 and the electrode 410 through deformation, thereby ensuring stable acquisition of the voltage signal. Therefore, by adjusting the bending height of the nickel sheet, flexible connection between the electrode 410 and the acquisition circuit board 300 can be achieved, ensuring the reliability of signal transmission.

[0086] As an implementable embodiment, referring to Figures 4 to 6 The acquisition device further includes a support 500, and the voltage acquisition piece 100 and the temperature acquisition piece 200 are connected to the acquisition circuit board 300 through the support 500.

[0087] Exemplarily, the support 500 provides mechanical support, ensuring that the voltage acquisition piece 100 and the temperature acquisition piece 200 are stably installed on the acquisition circuit board 300, preventing displacement or loosening during vibration or movement.

[0088] The position of the temperature acquisition piece 200 directly affects the accuracy of measurement. By setting the support 500, the support 500 helps the temperature acquisition piece 200 to remain in the optimal position to ensure accurate data acquisition. The support 500 can function as a fixing foot, making the relative position between the feet more accurate, facilitating production and use.

[0089] As an implementable embodiment, the support 500 includes a support body and a mounting portion, the support body is arranged on the acquisition circuit board 300, and the mounting portion is arranged on the side of the support body close to the acquisition circuit board 300; the support body is connected to the acquisition circuit board 300 through the mounting portion.

[0090] Exemplarily, the acquisition circuit board 300 is provided with receiving ends corresponding to the voltage acquisition piece 100 and the temperature acquisition piece 200, in order to facilitate the connection of the voltage acquisition piece 100, the temperature acquisition piece 200 and the corresponding receiving ends. The support 500 further includes a mounting portion, which can be a mounting column, and correspondingly, the acquisition circuit board 300 is provided with a corresponding mounting hole close to the receiving end on the acquisition circuit board 300.

[0091] In this way, the mounting portion provides a stable connection point, allowing the bracket body to be securely fixed to the acquisition circuit board 300. This ensures that the entire acquisition device remains stable during operation, reducing displacement or damage due to vibration or external forces, while at the same time, the bracket body is fixed to the acquisition circuit board 300 by the mounting portion, providing preliminary positioning for the voltage acquisition piece 100 and the temperature acquisition piece 200. This positioning helps to ensure that the voltage acquisition piece 100 and the temperature acquisition piece 200 are accurately aligned with the receiving ends on the circuit board, simplifying the installation process. Since both the voltage acquisition piece 100 and the temperature acquisition piece 200 are connected to the acquisition circuit board 300 through the bracket 500, this design reduces the complexity of independent connections, simplifying the wiring and connection process.

[0092] In some embodiments, the mounting portion can also be a mounting groove or the like, and the acquisition circuit board 300 can be a mounting protrusion or the like, which is adapted to be located in the mounting groove to connect the mounting portion and the acquisition circuit board 300.

[0093] In other embodiments, the mounting portion can also be a mounting port or the like, and the acquisition circuit board 300 can be a mounting column or the like, which is adapted to be located in the mounting port to connect the mounting portion and the acquisition circuit board 300.

[0094] Exemplarily, the bracket 500 comprises a plastic bracket. Plastic materials are generally lighter than metals, which helps to reduce the weight of the acquisition device. Plastic is generally cheaper than metal and easy to mass-produce. Using a plastic bracket can reduce production costs and improve economy. Plastic has electrical insulation properties, which is particularly important for the battery 400 monitoring system, as it can prevent electrical short circuits and other electrical interference. Plastic materials generally have good corrosion resistance and are not easily affected by chemicals.

[0095] As an implementable embodiment, the bracket body has a connection end for connecting with the voltage acquisition piece 100 and the temperature acquisition piece 200.

[0096] Exemplarily, the bracket body needs to have sufficient strength and stability to support the installation and operation of the voltage acquisition piece 100 and the temperature acquisition piece 200.

[0097] The connection end comprises a connection hole or a connection mechanism to ensure that the voltage acquisition piece 100 and the temperature acquisition piece 200 can be securely and reliably connected to the bracket body.

[0098] As an implementable embodiment, the connection end has a first connection hole; the voltage acquisition piece 100 passes through the first connection hole and is connected to the acquisition circuit board 300.

[0099] Exemplarily, the first connecting hole provides a fixing and positioning structure, enabling the voltage collection piece 100 to be stably mounted on the bracket body. Stable mounting and reliable electrical connection help to improve the overall reliability of the collection device and reduce signal loss or errors caused by poor connection.

[0100] By providing the first connecting hole on the bracket body, the voltage collection piece 100 can be conveniently connected with the collection circuit board 300. This design simplifies the wiring process and ensures the reliability of electrical connection.

[0101] In addition, by providing the first connecting hole on the bracket body, the collection device can reduce additional fixing components, thereby simplifying the overall structure. This not only reduces manufacturing costs but also reduces installation complexity.

[0102] By providing the first connecting hole on the bracket 500, the voltage collection piece 100 can be more easily mounted and dismounted, which helps to simplify the maintenance and replacement process.

[0103] In some embodiments, the voltage collection piece 100 is directly connected with the collection circuit board 300.

[0104] In other embodiments, the voltage collection piece 100 is connected with the collection circuit board 300 through the connecting end of the bracket body.

[0105] As an implementable embodiment, the connecting end has a second connecting hole; the temperature collection piece 200 passes through the second connecting hole and is connected with the collection circuit board 300.

[0106] Exemplarily, the second connecting hole provides a fixing and positioning structure for the temperature collection piece 200, enabling it to be stably mounted on the bracket 500. This ensures that the temperature collection piece 200 maintains a stable position during operation, avoiding displacement due to vibration or external force.

[0107] By providing the second connecting hole on the bracket body, the temperature collection piece 200 can conveniently pass through the bracket 500 and be connected with the collection circuit board 300. This design simplifies the installation process and reduces the need for additional fixing devices. The design of the second connecting hole can ensure that the temperature collection piece 200 is accurately aligned with the receiving end on the circuit board, ensuring reliable electrical connection and signal transmission.

[0108] The thin-film thermistor is a plug-in device, and the pins of the thin-film thermistor are inserted into the bracket 500 and connected with the bracket 500 by clamping force; the thin-film resistor pins are connected with the collection circuit board 300 by soldering.

[0109] As an implementable embodiment, with reference to Figures 7 to 10As shown, the voltage collection piece 100 includes a voltage collection section 110, which has a voltage collection end; the voltage collection section 110 is adapted to be connected to the battery 400.

[0110] Exemplarily, the voltage collection end of the voltage collection section 110 is directly connected to the battery 400, so that the voltage collection piece 100 can monitor the voltage of the battery 400 in real time. This is crucial for accurate assessment and management of the state of the battery 400. The voltage collection section 110 is responsible for transmitting the battery 400 voltage signal to the receiving end on the collection circuit board 300 for further data processing and analysis.

[0111] The voltage collection section 110 acts as an electrical interface, ensuring reliable connection between the battery 400 and the collection circuit board 300, supporting stable data collection.

[0112] As an implementable embodiment, the voltage collection piece 100 includes a voltage connection section 120, which is connected with the voltage collection section 110.

[0113] The voltage connection section 120 passes through the first connection hole and is connected with the collection circuit board 300.

[0114] Exemplarily, the voltage collection section 110 is directly connected to the battery 400 for real-time monitoring of the voltage state of the battery 400. The voltage collection section 110 is responsible for obtaining the voltage signal from the battery 400 and transmitting it to the voltage connection section 120.

[0115] The voltage connection section 120 passes through the first connection hole of the bracket 500, ensuring its stable positioning on the bracket 500. The voltage connection section 120 is connected with the collection circuit board 300 to transmit the voltage signal to the circuit board for processing and analysis.

[0116] Through the first connection hole of the bracket 500, the voltage connection section 120 can be stably fixed on the bracket 500, reducing displacement or damage due to vibration or external force. The voltage connection section 120 provides an efficient signal transmission path from the battery 400 to the collection circuit board 300, ensuring the integrity and accuracy of the voltage signal. This design simplifies the installation and maintenance process of components, and the modular design of the voltage connection section 120 and the voltage collection section 110 makes replacement and adjustment easier.

[0117] As an implementable embodiment, referring to Figure 3 and Figure 4 As shown, the voltage connection section 120 includes a first extension section 121, a second extension section 122, and a third extension section 123 connected in sequence; the extension directions of the first extension section 121 and the third extension section 123 intersect with the extension direction of the second extension section 122.

[0118] The first extension section 121 is connected to the voltage acquisition section 110.

[0119] The second extension section 122 is located on the side of the bracket 500 opposite to the battery 400.

[0120] The third extension section 123 passes through the first connection hole and is connected to the acquisition circuit board 300.

[0121] For example, the first extension 121 is connected to the voltage acquisition section 110 and is responsible for acquiring voltage signals from the battery 400. The design of the first extension 121 ensures a stable connection with the voltage acquisition section 110 and provides the starting point for signal transmission.

[0122] The extension direction of the second extension 122 intersects with that of the first extension 121 and the third extension 123, and is typically used to adjust the direction of the signal transmission path. The second extension 122 is located on the side of the bracket 500 away from the battery 400 to optimize space utilization.

[0123] The third extension 123 passes through the first connection hole on the bracket 500, ensuring that it can pass securely through the bracket 500. The third extension 123 is connected to the acquisition circuit board 300 and is responsible for transmitting the voltage signal to the circuit board for processing.

[0124] Through the combined design of the three extension sections, the voltage connection section 120 can flexibly adapt to different spatial layouts and installation requirements. This flexibility helps to achieve optimized wiring in complex internal equipment structures. The intersecting extension directions of the first extension section 121, the second extension section 122, and the third extension section 123 provide additional mechanical stability, reducing the risk of connection loosening or disconnection due to vibration or external forces.

[0125] By rationally arranging the voltage connection section 120, the limited space can be effectively utilized.

[0126] As one feasible implementation method, refer to Figure 7 , Figure 9 As shown, the temperature acquisition unit 200 includes a temperature acquisition section 210; the temperature acquisition section 210 has a temperature acquisition end, and the temperature acquisition section 210 is located on the side of the voltage connection section 120 away from the acquisition circuit board 300.

[0127] One end of the temperature acquisition section 210 is located on the side of the voltage acquisition section 110 away from the battery 400, and forms the temperature acquisition end.

[0128] For example, the temperature acquisition segment 210 is used to acquire the temperature of the voltage acquisition segment 110 in order to indirectly acquire the temperature of the electrode 410. One end of the temperature acquisition segment 210 is connected to the temperature connection segment 220, and the other end serves as the temperature acquisition end.

[0129] The position selection of the temperature collection end helps to evaluate the thermal state of the battery 400, especially during the charging and discharging process of the battery 400, the temperature change may affect the performance and safety of the battery 400.

[0130] As an implementable embodiment, the temperature collection piece 200 includes a temperature connecting section 220, which is arranged on the side of the voltage connecting section 120 away from the battery.

[0131] The temperature connecting section 220 is connected to one end of the temperature collection section 210 away from the temperature collection end; the temperature connecting section 220 is provided with a second connecting hole and is connected to the collection circuit board 300.

[0132] Exemplarily, the temperature connecting section 220 is connected to one end of the temperature collection section 210 away from the temperature collection end, responsible for transmitting the temperature signal to the collection circuit board 300. The temperature connecting section 220 passes through the second connecting hole of the support 500, ensuring its stable position on the support 500. The temperature connecting section 220 is connected to the collection circuit board 300, transmitting the temperature signal to the circuit board for processing and analysis.

[0133] As an implementable embodiment, the voltage collection section 110 has a welding part for welding with the electrode 410 of the battery 400.

[0134] The temperature collection section 210 is arranged at intervals with the welding part along the extension direction of the voltage collection section 110.

[0135] Exemplarily, the welding part is used to firmly weld the voltage collection section 110 to the electrode 410 of the battery 400, ensuring reliable collection of the voltage signal. Good electrical contact is provided through welding, reducing the contact resistance, thereby improving the accuracy of voltage measurement. The connection part of the electrode 410 and the voltage collection piece 100 is shown in the position of the dashed box B in FIG. 1. Figure 1

[0136] ​Exemplarily, in the process of welding the voltage collection section 110 and the electrode 410, for example, in the process of welding the voltage collection section 110 and the electrode 410 together by laser, a pressure head is used to press the nickel sheet to ensure the stability of the welding when laser welding. The temperature collection section 210 needs to be designed outside the range of the pressure head to avoid physical damage. At the same time, the temperature collection end cannot be welded at the connection between the welding part and the electrode 410, otherwise the temperature collection end will be damaged by the high temperature of the laser. Therefore, due to the high temperature generated by laser welding, the temperature collection section 210 must be kept a certain distance from the connection between the welding part and the electrode 410. This interval design helps to protect the temperature sensor from high temperature. Among them, the voltage collection section 110 and the electrode 410 can also be connected by reflow soldering and wave soldering. To adapt to automated production.
